intermediate the ends of said supportingy frame, independent latches being associated with said frame and kracks for securely locking the pane at any desired height and for thusprecluding any creeping thereof.V

The primary object of the invention is to provide a device of the aforesaid type having an improved rack. and pinion structure whereby the operative engagement of the pane frame and window or door supporting frame is rendered more eiiicient and consequently the raising or -lowering of the former slidably to the latter more secure and progressive.

A further object of the invention is toprovide a device of the aforesaid type having improved actuating means associated with the handle or knob whereby the raising of the pane frame is rendered easier and less tiresome particularly in the case of large and f heavy frames.

^ A still further `object of the inventionis to provide a device of the aforesaid type having improvedmeans for locking the pane frame at the desired height more easily i. e.

by means of a smaller strain and thus to preclude any creeping thereof.

Other objects and advantages ofthe inven tion will incidentally appear from the fol lowing description reference being had to the accompanying drawings wherein Figure l is a fragmentary yperspective view of the improved device showing the pane frame unit slidably mounted upon a stationary window pane. i y

Vwindow or e `grooves formed 1n said legs and cross beams Reference being had to these several figures wherein like references designate like parts, it must first be understood that the expressions outer and inner which will be found in the following description particularly as applying to the slidable pane `frame must be construed as corresponding to an" observer who would view the device respectively from without and from within the car. 'c The improved device is readily applicable to all windows or doors of motor cars or other vehicles fitted with vertically adjustable panes and will find a special utility in connection with large-sized panesy such as the Vpane `of the window surmounting the `partition between the driversy seat and theinside eeats in coupe cars, landaulet cars or the ite.

According `to the invention, the device comprises two distinct parts. The first part A of stationary structure is formed by an elongated metal framework (made of cast aluminum alloy for instance, adapted to be firmly secured by any suitable fastening means to the body of they car adjacent the window or door opening which is substantially equals in length so as to have its top edge flush with the lower edge of said open* ing by being concealed in the corresponding plain or upholstered part of the body.V The secondpart B of movable structure isformed by a metaly frame comprising two upstanding legs b yunited intermediate their ends and at' their upper ends by two cross beams b1, b2 so as to properly carry the glass pane P therebetween. As will be more fully described hereinafter, the movable part B is slidably supported by the stationary part A so as to cause the pane P to be vertically shifted with respect to saidstationar'y part A i. e.to the body ofthe car in which ythe latter is embedded.

Each of the upstanding-legs b of the movable part B has fixed against its outer edge by any suitable fastening means such las lscrews 2 or integrally lformed therewith a 'rack l the teeth of which are turned inwards.

beams: a lower cross beam b1 perpendicular thereto and an upper cross beamb2 conven iently of such a shape (a convex shape for instance) as to fit the upper edge of the door opening. kYVithin the s set a y,glasspane P. 'e

The stationary part A is substantially formed of a builtnup metal beam reinforced by struts a. Beth ends of the strutted beam are enlarged into shoulders which present two hollow portions: an inwardly directed narrow groove al the purpose of which will appear hereafter and a broader side groove a2 adapted to snugly embrace the upstandlng leg b and the contiguous rack 1 (see Fig. 1)

wherebythe movable part B is slidably supported in the stationary part A. Longitudinally extending throughout the latter somewhat to the rear of its innerk face as shown in F ig. 3 is a shaft 3 rotatably carried by bearing blocks d and provided inter- `mediate, its ends, preferably midway of its length, with a bevel pinion 4 meshing with a bevel wheel 5 fast upon a spindle 6 which projects at right angles to the beam A in asuitable casing C formed integral therewith orI fixed thereto. Said casing C has outer radial stiening ribs r and in its inner capacity is housed a suitably reckoned reducing-.gear preferably composed of three (or another odd number) intermeshing pinions 6, 7, 8 respectively mounted upon spin- .p dles 6', 7', 8 as dlagrammatically shown in Figure ,2, the spindle 8 being extended L,to such an extent as is governed by the very thickness of the plain or upholstered part of the car body to carry a crank and a handle H or alternatively a knob of more or yless decorated structure. Around the spindle 6 is coiled a spring of known construction (not shown)V housed inthe casing C and adapted to exert a braking edect on the reverse rotation of said spindle 6. Adjacent each end of the shaft 3 rotatably carried in aplug 9 is rigidlymounted a pinion 1() so positioned as to continuously mesh `with the respective rack 1. By this arrangement, it will be readily understood that by turning inthe proper direction the handle H both pinions 10 will be caused to rotate' and thus to move the racks 1 upwards thereby raising the pane frame B.

Longitudinally extending throughout the beam A somewhat rearwardly of ,its inner face as shown in Fig. 3 and parallel to the actuating shaft 3 is another shaft 11 rotatably carried in a pair .of slightly spaced bearing blocks e. Upon the port-ionrof the shaft 11 intermediate said bearing blocks e is rigidly mounted a. pinion 12 which meshes kwith the rack 13 and eatendedatone end into an enlarged head 1e to which is suit- The inner end of the bracket f has a.

ably attached an inwardly projecting lever 16 the purpose of which will presently appear. At its opposite end protruding from the boss f1, the spindle 111 has coiled thereon a small lspring 17 abutting against a. pin 17 so as to hold the rack 13 and pinion 15 in mesh.

Each end of the shaft 11 is rigidly fitted with a cam 18 adapted to engage an up standing lever 19 pivotally mounted upon a pin 2O and having its upper end tted with an elbowed member 21 suitably fixed thereto as by screws 21l or formed integral therewith the free straight end of which is provided with teeth of a pitch equal to that of the teeth of the rack 1 whereby said member 21 is adapted to act as a locking claw by intermeshing with the rack. The upstanding lever 19 is pivotally housed in the narrow groove L1 formed in the end of the beam A and submitted to theV antagonistic action of a plurality of strong springs 22.

By this arrangement, it will be understood that whilst normally, due to the action Vof the springs 22, the levers 19 hold the claws 21 in locking engagement with the rac-ks 1 thereby invariably maintaining the pane frame B at any desired height whilst absolutely precluding any creeping7 thereof, it is possible at anytime to readily unlock the racks 1 and theframe B to which they are secured by clearing the claws 21 oi therefrom by means of the aforesaid cam actuating device. All that is necessary for that purpose is to angularly displace the lever' 16 which to that effect is suitably shaped and placed in the car within easy reach of the passengers, thereby causing the shaft 11 to be rotated through the intermediary of the pinions 12, 15 and rack 13 and both cams 18 to swing the upper ends of the levers 19 and consequently the claws 21 away from the racks 1.

As will be appreciated the respective size of the pinions 12 and 15 and the length of the actuating lever 16 will be so calculated as to provide a suiiicient leverage for permitting the resistance of the several springs 22 normally holding the claws 2 1 in locking engagement with the racks 1 to be readily overcome merely by exerting a relatively small stress such vas the one a lady passenger for example can exert. The return of the levers 19 and theclaws 21 to locking engagement with the racks 1 and the concomitant stopping ofthe slidingmotion of the pane frame B will automatically take place under the action of the Ysprings 22 as soon as the actu ating lever 16 will be moved back to locking positiont y It will be readily understood that this device for `raising or lowering window panes being made up of a relatively small number ofstrong and easily mountable parts.

of small volume` and not liable to get out of order will operate very satisfactorily in all l. A raising and lowering device for win-` dow and like panes, comprising independent end members of channelformin cross section and an intermediate connecting member of channel form in cross section and fitted within the channel formation of the end members, each of the end members being integrally formed with a channel voffset from the longitudinal plane of the member and y opening inwardly towardthe member to slidably r'eceive a pane-carrying frame, the end members being further formed with an integral channel arranged in the longitudinal plane of the member and opening at right angles to said plane, said latter channel serving to house an operating means and a locking means for the pane frame.

2. A raising and lowering device for window panes and the like, comprising end sections of channel formation and an intermediate section of channel formation litting within and maintaining desired spaced relation of the end sections, each end section being formed with a channel opening toward the intermediate section and offsetfrom the plane of the end section and with a further channel arranged in the plane of the end section and opening in a direction at right angles thereto, a window pane frame slidably mounted in the first mentioned channel, a rack secured to the window pane frame with the teeth extending toward the second f channel, and operating means arranged in the second channel to cooperate with said teeth for raising and lowering the frame.

3. A raising and lowering device for window panes and the like, comprising end sections of channel formation and an intermediate section of channel formation fitting within and maintaining desired spaced relation of the end sections, each end section being formed with a channel opening toward the intermediate section and offset from the plane of the end section and with a further channel arranged in the plane of the end section and opening in a direction at right angles thereto, a window pane frame slidably mounted in the iirst mentioned channel, a rack secured to the vwindow pane frame with the teeth extending toward the second channel, operating means arranged in the second channel to cooperate with said teeth for raising and lowering the frame,-

actuating mechanism carried by the intermediate sect-ion, and connections between the actuating mechanism and operating means.

4. A raising and lowering device for window panes and the like, comprising end sections of channel formation and an intermediate section of channel formation fitting within and maintaining desired spaced relation of the end sections, each end section being formed with a channel opening toward the intermediate section and offset from the plane of the end section` and with a further channel arranged in the plane of the y end section and opening in a direction at right angles thereto, a window pane frame slidably mounted in the first mentioned channel, a rack secured to the window pane frame with the teeth extending toward the second channel, operating means arranged in the second channel to cooperate with said teeth for raising and lowering the frame, actuating mechanism carried by the intermediate section, and connections between the actuating mechanism and operating means, said connections being housed within the channel formation of the intermediate and end sections.

In testimony whereof I have signedr my name to this specification.
